PACK!NGv-IVIACI-liNEl1 SPECIFICATION forming part of Letters Patent No. 784,932, dated March 14, 1905.

Application filed November 24, 1903. Serial No,.l82,468.

To n/ZZ wir/071?, t 7mm/,f concern:

Be it known that I, DANIEL L. EUs'rIcn, a citizen of the United States,residing at Galena, in the county of Jo Daviess and State of lllinois, have invented new and useful lmprovements in Packing-Machines, of which the following is a specification.

My present invention is an improven'ient over an invention shown in an application iiled by me on the 15th day of July, 1903, and numbered 165,700; andthe improvement consists mainly in the table and in the mode of applying' the power to operate the table.

Vlt further consists in g'iving peculiar movements to the table whereby the table may be made to start slowly, then move rapidly, and then brought slowly to a standstill, or other convenient movements may be given to the table to accommodate it to different varieties of material or liquids to be packed and different movement necessary to carry out the design of the machine.

The following specilication, when taken in connection with the drawings accompanying' the same and forming a part hereof, will give in detail the manner in which it is constructed and the mode of its operation.

Fig'ure 1 shows a perspective view from one side of the machine. Fig. 2 is a perspective view 'from the opposite side of Fig. 1, showing' part of the traveling tables and frame cut away to show the weighing mechanism and the device 'for bring'ing the tables into gear. Fig'. 3 is a perspective view showing the mode of advancing the tables and of giving them a variable movement. Fig. 4 is a perspective view of one of the shafts for operating' the table with the plates on top of the shaft and its connection with the weighing' and feeding mechanism. Fig'. 5 isa perspective view taken from the opposite side of Fig. 4 and showing' means for operating the other table. Fig'. 6 isa perspective view of one set of the plates mou n ted upon one of the operati iig-shafts an d showing the arm in the groove and the locking-pin raised. Fig. 7 is a perspective view of the outer tube of the feeding' mechanism. Fig. 8 is a longitudinal section of the feeding' mechanism. Fig'. 9 is a perspective view of the inner tube of the feeding' mechanism and showing the inlet and d ischarg'e openings. Fig'. 10 is a perspective view of the locking'- pin. Fig'. 11 is a perspective view of the gears for advancing' the table at a variable rate of speed. Fig'. 12 is a plan view of one of the plates comprising' the table. Fig'. 13 is a perspective view of a modification of Fig'. 12. Fig. la is a transverse section of the endless tables and their supporting' means.

Referring' to the drawings, the frame, which consists of two side bars 2, one on each side of the tables, is secured to standards el. The side bars 2 are stayed at intervals by crossbars 3, as seen in Fig'. 1&1, disposed at right angles to the side bars beneath the tables and to which the side bars are also fastened. Along' on the top of each side bar 2 is secured a metal strip 5, and in the center between the side bars 2 is an inverted-T-shaped strip 6, rigidly secured to the cross-bars 3, and upon these strips 5 and G thecndless tables presently to be described travel.

The tables S and 10 consist of plates or links 12, provided with openings 13 near their center, which plates are hinged or linked together by forming' a slot 14e in one end of the plate and upon the other end a hook 15, adapted to engage in the slot 1i of a contiguous plate. rlhese plates when united tog'ether form an endless flexible table. There are grooves l1. around the holes` 13 for determining' the position the packageis to occupy when itis being' lilled.

Then it is desired to lill two or more cans at the same time and with one weighing meehanism, using' only a single table, these plates or links 12 are widened out, as shown in Fig'. 13. They would still have but one opening' 13 theretl'u'ough; but this opening' 13 would' be in one side, and a space 9 at one side of the link on which the other cans to be filled are set. rlhere may be a groove 11 inthe plate for convenience in determining' where the can shall bc set. .ln this manner all the cans upon any plate may be iilled at the same time. ln Fig. 13 l have shown only plates for two cans; but it is manifest that the plates may be wide and long' enough to sustain a number at the same time.

Atene end of the frame is jourualed in the roo il. nu

side bars and standards 4 a shaft 16, and upon this shaft are loosely mounted sprocket-wheels 18, one for each table, which wl'leels are each provided with sprockets 20 set the same distance apart as the distance between the openings 13 in the plates, so that the sprockets will engage theopeningsin the plates. ltisnotaneccssity that these be sprocket-wheels, as it is manifest that they may be drums or any other convenient arrangement for the tables to travel over. At the opposite end of the machine are journaled two shafts 21 and 22 in the side bars 2 and standards, and on the shaft 22 is rigidly mounted a sprocketwheel 24, the sprogkets 20 of which engage the openings 13 in the table 10 and advance the same when power is applied to the sprocket-wheel 24. 0n the shaft 21 is rigidly mounted another similar sprocket-wheel 25, having sprockets adapted to engage the openings 13 in the plates which form the table 8 and advance said table.

For the purpose of advancingI the tables there is secured upon a platform 26 bearings or standards 28, in which a shaft 30 is set to rotate. The outer ends of this shaft 30 are provided with worm-gears 32 and 33. Through the platform 26 near the worm-gear 32 is set a shaft 34 and near the gear 33 another shaft 35.

Upon the top of the shaft 34 is rigidly secured a circular plate 36 and on the shaft 35 a similar plate 38. These plates are each provided with a groove 40. On the shafts 34 and 35 below the plates 36 and 38 are loosely mounted plates 41 and 42, each provided with a gear 44. These plates are also provided with one or more notches or recesses 45. The plates 36 and 38 are recessed out, and in each of said recesses is loosely inserted a rectangularly-shaped pin 46, (shown in Fig. 10,) in which is a recess 48. Said pin is adapted to engage the recesses 45 in the plates 41 and 42.

0n the top of each of the plates 36 and 38 is placed a spring 50, adapted to rest on a pin 46 and hold it in engagement with one of thc recesses 45 in the plates 41 and 42. Upon the shaft 30 is mounted a pulley 51, which is belted to the power by a belt 52.

Upon the lower end of each of the shafts 34 and beneath the platform 26 is secured a gear (Shown in Fig. 11.) This gear is of oblong or elliptical shape and is mounted upon its shaft near one end and adapted to mesh in lwith a gear 56 of substantially the same shape.

form 26 is also secured a standard 64, and in the top of said standard is pivoted an arm 65 of chisel shape at the end 66 and provided with a pin 68, set on top near the middle of the arm. There are two of these standards, one near each plate 36 and 38, so set on the platform that the arms 65 will engage the grooves 40 in the plates 36 and 3L. For thc purpose of holding' these arms in engagement with the grooves 40 there is secured to each arm a coil-spring 70, attached at the other end to a post 72.

The weighing mechanism consists of a platform 75, upon which are set two uprights or standards 76. These standards are connected together by a bar 78, and to this bar are pivoted balance-beams 79 and 80. To the beam 79 is attached a weight 81, and to the beam 80 is a weight 82. To the outer end of the beam 79 is secured a bar 84, upon the top ol which is a platform 85. The beam 80 has upon its outer end a like bar 86, upon the top of which is a platform 87. To the standards 76 are also pivoted two bars 88 and 89. To the bar 88 is pivoted a bar 90, loosely attached to the base of the bar 84, and to the bar 89 is attached a similar bar which is adapted to loosely engage the bar 86 at the opposite end ofthe platform 87.

In order to apply the power and bring the gears which advance the tables into operative engagement and to operate the feeding' or lilling cut-olf at the same time, there is attached to the bar 86 an arm 92, which projects forward and engages a loop 93, and upon the bar 84 is attached an arm 94, which also projects forward and engages a loop 95. l/Vithin the traveling tables there is hung a platform 96 by hangers 98, attached to the side pieces`2.

' Upon this platform are two standards 99, in

which is journaled a shaft 100 and on which are secured two ratchet-wheels 101. Upon the same platform are set two other journalbearings 102, in which is journaled a shaft 103. one end an arm 104, to the outer end of which is pivoted an arm 105, terminating in a hook or ratchet 106, adapted to engage a ratchetwheel 101 on the shaft 100. On said shaft 103 is loosely mounted a sleeve 110, to which is secured an arm 108. To the outer end of this arm is pivoted an arm 112, carrying' a hook or ratchet 114, adapted to engage one ol the ratchet-wheels 101 on the shaft 100. The arm 105 carries the loop 93, and the arm 112 carries the loop 95.

The sleeve is provided with a lug or arm 115, to which is pivoted a bar 116, that extends backward and is pivoted to a crank 118, pivoted near the top of the standard 99. Upon the outer end of the shaft 103 there is secured a lug 120, which is attached to the crank 118 by a bar 122.

It will be observed that as the arm 108 is attached to a sleeve upon the shaft 103 and On the shaft 103 is rigidly fastened near lOO the outer end of said shaft is attached to the crank 118 by the rod 122 and the sleeve is attached to the same crank 118 by the rod 116 and as the arm 104 is rigid on the shaft 103 when this arm is drawn forward by the rotation of the wheel`101 the same movement will draw back the arm 108, as shown in Fig. 2.

Upon the shaft on the outside of the frame is secured a sprocket-wheel 124, which is belted by a sprocket-belt to a sprocketwheel 126, set upon a shaft 127, and is preferably operated by the power which operates the feeding' mechanism.

Upon the outer end of the shaft 103 is mounted a circular plate 128, provided with two notches 131, with which a springhook 132 is adapted to engage. At the outer end of the shaft 103 is secured an arm 133, and to the end of this arm is loosely attached a tube 134, into which a rod 135 telescopes for adjustment in length and is held in the required adjustment by a set-screw 136. This rod 135 is loosely attached to an arm 138,which is secured to a shaft 140, attached to the end of the cut-off of the feeding mechanism presently to be described. ln the end of the shaft are two pins 141 and 142, set on opposite sides from each other on a plate 143.

For the purpose of operating the feeding mechanism whereby the flow of the axlegrease or other filling material is cut off from lilling one can upon one table and open to lill the can on the other table there is attached to the standard 72 a coil-spring 144, to which is loosely secured a bar 145, provided with a notch 146, adapted to engage the pin 68 upon the arm 65, which engages the groove 40 in the plate 36. The outer end of the bar is loosely attached to a swinging standard 148, pivoted to the platform 26 by the pivot-pin 149. There is attached to the bar 148 a cord or rope 150, which is secured at its other end to a pin 142 on the plate 143.

To the standard 152 is attached a coil-spring' 153 and a similar bar 154, attached to the standard 155, pivoted in the platform 26. The bar 154 is provided with a notch (not shown, but the same as notch 146) adapted to engage the pin 68 upon the arm 65, which engages with the slot 40 in the plate 38. To this standard 155 there is attached a cord 156, which is connected to a pin 141 upon the plate 143.

For the purpose of aiding in operating the weighing mechanism and to hold down the platform 85 while the table is advanced there is secured on the shaft 58 a circular plate 158, provided with a rim in which is a rounded y notch or depression 159.

A rod 162 is pivoted in a bearing 163`and provided with an arm 164, adapted to engage the under edge of the rim and enter the notch 159. The rod 162 extends underneath the table to the opposite side of the frame, passing through bearing 165. Near the end of this bar 162 is attached an arm 166. This arm is connected by a bar 168 to an arm 170, hinged to a hanger 171. The outer end of the arm 170 rests upon the arm 90. 1t will be seen that when the plate 158 is rotated by the shaft 58 the bar 162 will be partially rotated by the engagement of its arm with the plate 158 when the arm enters the notch 159, and this will draw down upon the arm 90 and hold the platform 85 down while the table is advanced. Then when the arm is forced out of the notch by the rotation of the plate 158 the arm 90 will be released.

To the shaft 60 is attached a plate 168, similar to the plate 158. This is connected by a bar 172 to the arm 174, which bears upon the arm 91 to hold down the platform 87 while the table 10 is traveling, the same as the platform 85 is held down by the arm 170. To

this bar 172 is attached an arm 17 3. adapted to engage the notch 171 in the plate 168.

The filling or feeding mechanism may be of any convenient construction, such as shown in my above-mentioned application. A simple device for use in lilling cans with liquids in this machine is shown in Figs. 7, 8, and 9 and consists of a supply-tank 175. Beneath this tank is set a tube 178, which is connected to the tank by a tube 180. 1V ithin the tube may be arranged an ordinary valve for the purpose of controlling' the supply of the filling' material. This tube 178 is provided on its under side with two discharge-openings 181 and 182. Tithin this tube is placed another tube 184. To the forward end of the tube 184 there is secured a cap 185, which is of sufiicient thickness to form a shoulder 186, against which the tube 178 contacts and prevents the inner tube from further entrance into the tube 178. The other end of the tube 184 is provided with a similar cap 188, to which is secured the shaft 140 for partially rotating the tube 184. The tube 184 is also provided with an inlet-opening, but it is of double the size of the inlet from the tank and coincident with said inlet, so that when the inner tube is partly rotated the openingl will still be coincident with the inlet from the tank and outer tube. The tube 184 is also provided with two discharge-openings 190 and 191, formed at the same distance from the rear end that the openings 181 and 182 are from the same end of the tube 17 8, the openings 190 arranged to discharge the contents of the tube 184 through the openings 181 and the opening 191 through the opening 182. The openings 190 and 191 are not in alinement with each other, but the openings 181 and 182 in the tube 178 may be. lt will be seen by this mode of construction that the material to be packed will pass from the tank through a valve in the tube into the tube 184, and when the tube 184 is partially rotated till the opening is coincident with the opening' 181 the material will be discharged into a can placed upon one of the tables, and when TOO IIO

the opening 191 is coincident with the opening 182 it will discharge it into another can placed upon another table.

The mode of operating my device is substantially as follows: Power is applied to the belt 52, which operates the pulley 51 and the shaft 30, and as the worm-gears 32 and 33 are attached to the outer ends of the shaft 30 and also engage the gears 44 upon the plates 41 and 42 the rotation of the shaft 30 will rotate the plates 41 and 42, and when the pins 46 are in engagement with the plates 41 and 42 they will both be rotated and at the same time rotate the shafts 34 and 35 and gears 55 and 56, which will also rotate the shafts 58 and 60. Since the shafts 58 and 60 are in engagement with the wheels 62 and 63 on the shafts 21 and 22, the shafts 21 and 22 will be rotated. They in turn will rotate the sprocketwheels 24 and 25 and advance the tables 8 and 10, but not at the same time, from the fact that the arm 65 does not engage the groove 40 in the plate 36 at the same time .that the similar arm 65 engages the groove 40 in the plate 38. The locking-pin 46 does not lock the plates 36 and 41 at the same time that a similar pin 46 locks the plates 38 and 42, and hence while one set of the plates 36 and 41 are being rotated there will be no rotation of the plates 38 and 42. Therefore when the table 10 is in motion the table 8 ceases to move and cannot move until the table 10 has ceased to move. Thecans to be filled are then placed over the holes 13 on both tables, and as one of the tables advances a can will be drawn along until it comes to the place where the platform 85 is arranged to pass up through one of these openings 13. The table 8 then has ceased its motion, because the arm 65 has entered the groove 40 in the plate 36 and has raised the pin 46 out of engagement with the holes 45 in the plate 41, and hence the plate 36 has ceased to rotate, which stops the rotation of the sprocket-wheel 25, which advances the table 8. The table 8 will not move again until after the can is filled, as the spring holds the arm 65 in engagement with the groove 40, and the arm is not released from engagement with the groove until after certain operations are performed by other parts of the machinery caused by the filling of the can to such an amount as to force down the platform 85. Then the can is filled till the contents are equal to the weight 81, it will force down the platform 85, and at the same time the arm 94 will also move down in the loop 95 and permit the arm 112 to fall by its own gravity till the ratchet 1 14 engages the ratchetwheel 101 on the shaft 100, and as the ratchetwheel is continually in rotation the ratchetwheel will draw forward the arm 108, and the sleeve 110 will force back the connecting-rod 116 and partially rotate the shaft 103 until the catch 131 on the spring-arm 132 has engaged in another notch 130 on the wheel 128. This partial rotation of the wheel 128 will turn the arm 133, drawing down the tube 134, and with it the rod 135, which will slightly turn the arm 138 and partially rotate the shaft 140 and cut off the flow of the filling material into the can through the opening 190 in the tube 184 and the opening 181 in the tube 178 and turn it into a can resting upon the table 10 over the platform 87 through the openings 191 and 182. The rotation of this shaft 140 willdraw the cord or connection-chain 150 and pull forward the standard 148, and with it the bar 145, and as the pin 68, which is attached to the arm 65, is in engagemei'it with the notch 146 in the bar 145 when this bar is drawn backward it will pull the arm 65 out of engagcmel'it with the groove 40 in the plate 36 and allow the pin 46 to he forced down by the spring 50 into engagement with one of the openings in the plate 41, and this will cause the shaft 34 to again rotate and by its connection with the sprocket-wheel 25 will advance the table 8 till the plate 36 has rotated sul'liciently to have the lug 67 come in contact with the bar 145 and release the pin 68 from engagement with the notch 146, which will allow the spring 70 to come into action and draw the arm 65 into engagement with the groove 40 in the plate 36, and thereby raise the pin 46 out of engagement with the plate 41, and the shaft 34 will cease to rotate, and the sprocket-wheel 25, with the table 8, will have come to a standstill. At this time the arm 164 upon the rod 162 has come into engz'rgci'nent with the notch 15S) in the circular plate 158, and said rod 162 has been partially rotated, turning the arm 166 and bringing down the arm 170 upon the arm 90, holding it down in that position, where it will remain until after the table 8 has heen moved. At this time the filling' device has commenced to lill a can placed upon the table 10 over the platform 87, which now projects up through one of the holes 13 and snstains the can. As soon as it is lilled to the amount of the weight 82 the platform 87 will be forced down, and with it the arm 92, within the loop 93 and permit the arm 105 to fall by its own gravity and the ratchet 106 to engage the ratchet-wheel 101 on the shaft 100. lt will draw forward the arm 105 and also the arm 104 and rotate the shaft 103, which will at the same time rotate backward the wheel 128 in the opposite direction into the notch 131. This will raise the arm 133 and force up the tube 134 with the rod 135 and partly rotate the shaft 140 and change the flow of material into acan on the adjoining table. lt will also draw back the post 155, and with it the bar 154, and bring the arln 65 out of engagement with the groove 40 in the plate 38 and allow a pin 46 to be forced into one of the openings 45 in the plate 42, and this action will commence to rotate the shafts 35 and 60 and the shaft 22, with the sprocket-wheel 24, and advance the table 10. l t will bescen IOL) llO

that only one of these tables can be advanced at the same time, and neither' table advances while any one of the platforms is above the surfaces of the tables.

In order to control the movements of the tables and start them slowly, then increase their speed, then bring them slowly to a standstill, so that there shall be no sudden start to spill out the liquid that may be in a can when filled, there is arranged upon the shaft 3e a gear 55 of nearly an ellipse shape, as shown in Fig. ll. Meshing in with this is another gear 56 of similar shape, which is mounted upon the shaft 58 near one end of the gear 56. The shaft 58 operates the table 8. rlhe mode in which these two gears 55 and 56 operate to give motion to the table is substantially as follows: When the portion of the gear 55 engages the gear 56 at the farthest distance from the shaft 84, it will turn the gear 56 more rapidly than one nearest to the shaft, and the table commences to move when the gear 55 is in engagement with the gear 56 nearest to the shaft 34, and when the table stops it will be in the same position, having traveled once around. Hence the table will be given a very slow movement at starting and gradually increasing to a rapid movement and decreasing slowly till it ceases to move. In this manner there will be no sudden jerks of the can to displace it from the platform or to disturb the contents if a liquid.

It will be observed that each table is moved separate and independent of the other tables and each given an intermittent movement or what may be termed a progressive step-bystep feed and at a variable speed, starting slowly, then increasing to a rapid movement, and then ending with a slow movement. It will further be seen that tables are advanced alternatively, and the construction is such that one table after it has removed a package from the filling mechanism the distance between two openings in the table cannot move farther till after the other table has also forwarded a filled package the same distance.
